Infinite mass in Coop

[Cantor]

I played Coop as UEF alone (1 player) and after some time I got infinite mass. Every half second the mass bar would fill up completely, or at least it looked like that. I could build mavors with 20 support commanders without my mass bar going lower than 90%.

It would probably be helpful if other people who experience this make a reply with the conditions in which they got unlimited mass. One guy in the chat mentioned that it happened when the GC showed up. I may have gotten infinite mass around that time, but I don't remember exactly.

(another problem for me was that the civilian trucks wouldn't move, but maybe I was just too stupid to figure out how to make them move)
